What is the difference between 87 89 and 91 gas?
What is the difference in octane levels? Octane is how much compression a fuel can withstand before igniting, or rather it’s a measurement of a fuel’s ability to avoid knock. Typically “regular” gas is 87 octane, “midgrade” is 89 octane and over 91 octane is “premium” gasoline.
What’s the difference between 87 and 93 gas?
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
What happens if I put 91 octane in my car?
“Use premium unleaded gasoline with a posted octane rating of 91 or higher. If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.”
What happens if you put 89 gas in a 91 car?
Using regular gas in an engine that requires premium could void your warranty. That is most likely to happen if using regular causes severe engine knock or pinging (premature ignition of the fuel, also known as detonation) that damages the pistons or other engine parts.
What happens if you put 91 octane in a 93 octane car?
If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.
Can you run 91 octane on a 93 octane tune?
Never use a octane lower than what’s prescribed by the tune. You may use a higher octane than prescribed by the tune. For example, running 93 Octane (R+M)/2 on a 91 Octane (R+M)/2 program is fine, and in some cases may offer a bump in performance.
